I got it and it literally worked for a week. Then I had to reopen my phone and put the previous one back in, which was already 3 years old but worked better than the new one that was obviously forgotten on some shelf and had expired...

It works fine, lasts as needed even in summer conditions - full heat at the sea, car etc - I didn't see any strange behavior. The big downside is that it doesn't charge quickly like the factory one, it takes 2 hours for a full charge. Otherwise, it will do its job.
